Follow Steps 4 and 8 in the Service Manual.
20 FBC-30-B
Warner Electric’s FBC series of Electrically
Released Modules are designed to be used in
clutch-brake combinations only. The FBC
modules can be mounted on a C-face motor
with the proper input module (10 module), and
can also be foot mounted with a 30 Input Clutch
Module and base. The FBC modules include a
spacer for mounting to 10 and 30 clutch
modules. The fail safe brake engages when
power goes off.
10-20 FBC
Reference: Electro-Module Service Manual
P-213.
Mounting Instructions
Follow Steps 1 and 2 in the Service Manual.
Step 3
Assembling two modules. The 20 FBC brake
module may be assembled to the mounted
model 10 motor clutch module as follows:
Reference: Electro-Module Service Manual
P-213.
Mounting Instructions
Follow Step 2 in the Service Manual.
Step 3
Assembling two modules. The 20 FBC brake
module may be assembled to the (30) input
clutch module.
A. Position the modules with the ventilation
holes down when in their normal horizontal
position to prevent foreign matter from falling
into the units.
B. Assemble the 20 FBC brake module to the 30
input clutch module, inserting the spacer
provided between the units. Bolt the modules
together with the long hex head bolts provided.
Follow Step 4 in the Service Manual.
A. Position the modules with the ventilation
holes down when in their normal horizontal
position to prevent foreign matter from falling
into the units.
Step 7
B. Assemble the 20 FBC brake module to the
motor clutch module, inserting the spacer
provided between the (20) and (10) modules.
Bolt the modules together with the long hex
head bolts provided.
A. Mount the modules so that the base is
located below the ventilation holes. A pilot
diameter on the end of each module mates with
pilot diameter on the base.

B. Secure the base to the modules with the four
(4) bolts provided.
Control Requirement
Electrically Released Permanent Magnet Brakes
must use one of Warner’s adjustable power
supplies. See the Service Installation sheet
included with the power supply for connection
information.
Note: All Electrically Released Permanent
magnet modules are polarity sensitive.
Therefore, the (+) wire must be connected to
the positive terminal and the (-) wire to the
negative terminal. Potentiometer control will
then provide adjustment for the proper brake
release point.
Switching of clutch and brake with this type of
module should allow both clutch and brake to
be engaged and disengaged simultaneously for
proper operation.
Brake Release Adjustment
Instructions for setting the optimum release
voltage of permanent magnet applied/
electrically released brakes.
The following procedure will
result in the brake releasing and allowing the
load to be free to move. Be sure the load is in
a safe condition before proceeding with this
process.
In a permanent magnet applied/electrically
released brake, the attractive force between the
brake surfaces is created by permanent
magnets. The brake is electrically released by
applying DC power to the electro-magnetic coil

in the brake that opposes the permanent
magnets. Electrically released brakes are
polarity sensitive: the positive lead of the power
supply must be connected to the positive lead
of the brake, and the negative lead of the power
supply must be connected to the negative lead
of the brake. The power supply applied to the
brake must also be adjustable so that the
optimum release voltage for each individual
brake can be determined and set.
The following procedure describes how to set
the adjustable power supply to the optimum
release point of the brake. A volt-meter is
required to perform the procedure.
No power is applied to motor
during this procedure. Power normally
supplied by motor to brake control should be
supplied by alternate method.
After control is adjusted per steps below,
brake control may need to be fine tuned
(adjusted) with motor running to compensate
for any changes in supply voltage used.
1. With power off, connect the positive lead of
the power supply to the positive lead of the
brake and the negative lead of the power
supply to the negative lead of the brake.
2. Connect a volt-meter to measure the voltage
applied across the brake.
3. Adjust the power supply to its lowest
possible output, then energize the power
supply only, to apply power to the brake.
4. Starting from the low point, slowly increase
the applied voltage until the brake armature
disengages from the magnet. Note and
record the applied voltage at this point.

5. Continue to slowly increase the applied
voltage until the armature re-engages the
magnet. If the maximum voltage available
from the supply does not cause the armature
to re-engage, the armature should be
manually assisted into engagement.
Note: If armature needs to be manually
assisted, armature should be pressed on
back side to make contact with friction face
of magnet.
6. With the armature re-engaged, slowly reduce
the applied voltage until the armature
disengages from the magnet. Note and
record the applied voltage at this point.
7. The optimum release point for the brake is
half-way between the two recorded voltage
readings. Adjust the supply to this optimum
release voltage.
Note: The above procedure should be done
by visually watching the armature move and
may be repeated if necessary from Step 1
through Step 7.
If any problems should occur during
adjustments or application questions arise,
please contact Technical Support at 1-800-8259050 Monday through Friday 7:30 a.m. - 4:30
p.m. central time.
